摘要:The present invention relates to non-naturally occurring polypeptides useful for preparing armodafinil, polynucleotides encoding the polypeptides, and methods of using the polypeptides. The non-naturally occurring polypeptides of the present invention are effective in carrying out biocatalytic conversion of the (i) 2-(benzhydrylsulfinyl)acetamide to (−)-2-[(R)-(diphenylmethyl)sulfinyl]acetamide (armodafinil), or (ii) benzhydryl-thioacetic acid to (R)-2-(benzhydrylsulfinyl)acetic acid, which is a pivotal intermediate in the synthesis of armodafinil, in enantiomeric excess.

标题:Synthesis of chiral N-protected-α-substituted-glycine free acids by zinc-mediated addition of organic halide to glycine cation equivalent
发明人:ABOOD NORMAN A; NOSAL ROGER A
权利人:SEARLE & CO
摘要:A method is described for synthesis of N-Boc-L-propargylglycine, a key intermediate used in the preparation of high-potency, orally-active renin inhibitors. This method involves reaction of an organic halide with a glycine cation equivalent, such as methyl N-Boc-2-acetoxyglycine, in the presence of zinc dust to give Boc-protected amino acid derivatives in high yield. Typically useful organic halides are allylic, benzylic and propargylic halides. Resolution of methyl N-Boc-propargylglycine with alpha -chymotrypsin provides N-Boc-L-propargylglycine in high yield.

摘要:The present invention relates to synthesis of β-amino acid derivatives of formula (I) and its salts of formula (Ia) by a novel process. The process comprises the reduction of a protected or unprotected prochiral β-amino acrylic acid or derivative there of, by using borane containing reducing agents at atmospheric pressure. The resulting racemic β-amino compound is resolved to a pure stereoisomer of formula (I), specifically to (2R)-4-oxo-4-[3-Ctrifluoromethyl)-5,6-dihydrol[1,2,4]triazolo[4,3-alpyrazin-7(8H)-yl]-1-(2,4,4-trifluorophenyl)butan-2-amine. In an embodiment the invention disclosed polymorphic forms of formula (I), phosphate salt of formula (I) and also a Dibenzoyl-L-tartaric acid salt of formula (I).
